Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

Bayou Corne in Louisiana, October 2010. In usage in the Southern United States, a bayou (/ ˈ b aɪ. uː, ˈ b aɪ. oʊ /) [1] is a body of water typically found in a flat, low-lying area. It may refer to an extremely slow-moving stream, river (often with a poorly defined shoreline), marshy lake, wetland, or creek.
A fen is a type of peat-accumulating wetland fed by mineral-rich ground or surface water. [1] [2] It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, are also known as mires. [2] The unique water chemistry of fens is a result of the ground or surface water input.
There are four main kinds of wetlands – marsh, swamp, bog, and fen (bogs and fens being types of peatlands or mires). Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types. [1] Sub-types include mangrove forests, carrs, pocosins, floodplains, [1] peatlands, vernal pools, sinks, and many others. [22]
A fen is one of the main types of wetland, the others being grassy marshes, forested swamps, and peaty bogs. Along with bogs, fens are a kind of mire . Fens are usually fed by mineral-rich surface water or groundwater.
The word palustrine comes from the Latin word palus or marsh. [2] Wetlands within this category include inland marshes and swamps as well as bogs , fens , pocosins , tundra and floodplains . According to the Cowardin classification system , palustrine wetlands can also be considered the area on the side of a river or a lake, as long as they are ...
The main wetland types include swamps, marshes, bogs, and fens; and sub-types include mangrove, carr, pocosin, and varzea. The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth.
The main types of intertidal wetlands are mudflats (e.g., mangrove swamps) and salt marshes. The mangrove swamps are encountered along tropical shores and are characterized by tree vegetation, while salt marshes are mostly found in temperate zones and are mostly grass ecosystems. [1] Intertidal wetlands are commonly encountered in most estuaries.
